You cannot escape the responsibility of tomorrow by evading it today

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

Hope might be a good breakfast, but it makes a very poor dinner

Tomorrow is worth more than yesterday but less than today.

Hard work - a two way street where you get exactly what you put in.

Success can never happen without the journey (struggle).

Lose an hour in the morning and you will spend all day looking for it.

Hard work beats talent when talent doesn't work hard.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

Failure to prepare = preparing to fail

In order to become better than anybody else you must first become better than yourself.

Failure is NOT your destiny. Failure is the key to success.

Don’t hang your targets after you’re done shooting.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

Don't fear failure, fear being in the same exact same place next year as you are now.
